A jury verdict that found the Port Authority more responsible for the 1993 World Trade Center bombing than the terrorists behind it should be upheld because the agency ignored numerous warnings of such an attack, victims’ lawyers argued yesterday.

“We expect terrorists to act like terrorists, and the Port Authority should have expected it. We should have expected better from the Port Authority,” victims’ lawyer Brian Shoot told a panel of appeals-court judges.

He urged them to deny the PA’s bid to throw out a verdict that found the bistate agency 68 percent responsible for the Feb. 26, 1993, bombing.

PA lawyer John Gibbons told the five-judge panel that the agency had done all that was necessary after various security reports found the buildings’ underground garage was at risk of attack, and that was “the minimum.”

“We took the minimum precautions,” he said, noting the agency had assigned a single security guard to patrol the sprawling, multilevel garage.

He said more precautions weren’t necessary because none of the security reports the agency had commissioned over the years had found an attack was “likely.”

Shoot noted the reports might not have used the exact term “likely,” but the agency had been warned the buildings were considered “a crown jewel for terrorists” and were “an iconic target.”
